ABSTRACT:
A method for the forming of semi-solid nucleated metallic alloys that have been sprayed in molten form into a container for intermediate casting. According to the present invention, a molten stream of metallic alloy is disrupted into a plurality of molten metallic alloy droplets, and the droplets are partially solidified as a plurality of degenerative dendritic globules so that approximately 5% to 60% by volume of each average degenerative dendritic globule is solid and the remainder is molten. The partially solidified globules are collected to form a semi-solid mass, and a portion of the semi-solid mass is forced into a die cavity prior to solidification to form a shaped metallic alloy.
